Rockwell Automation 1769-SM2 Compact I/O DSI/Modbus Communication Module - Manual (Page 14)

1-2 Getting Started
The 1769-SM2 Compact I/O to DSI module features include:
•
Three Compact I/O connection channels for PowerFlex 4-Class
drives. Up to 3 drives can be connected in Single mode (1 per
channel) and up to 15 drives can be connected in Multi-Drive mode
(5 per channel). Any channel in Multi-Drive mode can also be
configured to operate as a Modbus RTU Master, allowing
connectivity to a maximum of 31 other Modbus RTU Slave devices,
such as PowerFlex 7-Class drives with 20-COMM-H RS485 HVAC
adapters.
•
Use as expansion I/O on MicroLogix 1500 and CompactLogix
controllers or with a remote 1769-based adapter. It receives the
required power from the Compact I/O backplane.
•
Parameter-configurable I/O, including Logic Command/Reference
and Logic Status/Feedback for each connected drive.
•
Explicit messaging (parameter read/write, etc.) support for:
– MicroLogix 1500 LRP Series C systems when used with
RSLogix 500 v6.30 (or higher)
– Enhanced CompactLogix processors, such as the -L31, -L32E,
and -L35E
Explicit messaging is NOT available for CompactLogix -L20 and
-L30 processors, or 1769-ADN DeviceNet adapters.
•
User-defined fault actions to determine how the module and
connected drives respond to controllers in idle mode (Idle Action).
•
Bi-color (red/green) status indicators to report the status of the
module and channel communications.
•
Compatibility with various configuration tools to configure the
module and connected drive(s). The tools include an optional,
external PowerFlex 4-Class HIM (22-HIM-A3 or 22-HIM-C2S), and
drive-configuration software such as DriveExplorer v3.01 (or higher)
or DriveExecutive v4.01 (or higher).
